Viewing the creative industries as a strategic sector for social and economic growth is a relatively new field of research, with both national and international bodies looking at how copyright industries can be seen as national wealth generators.
In a series of studies on the contribution of creative industries to national economies, the World Intellectual Property Organization (WIPO) proposed a methodology for classifying the creative industries on the basis of their dependence on copyright-protected content: "Core," "Interdependent," "Partial" and "Non-dedicated support."
In the core industries group, the Press and Literature sector is by far the biggest contributor to national GDP with a share of 40.5%.
